Diets like a protein sparing modified fast can have you going for 1.5-2g/lbs, just because your primary source of fuel is body fat and amino acids, as such you've gotta get quite a bit more since they're mostly being oxidized.

Of course, that's an extreme. Even then at 2g/lbs (the higher end) he'd only eat about 440 a day, which is still a $h1t.

yeah Nightfall, I think you must've missed my post earlier. I spoke to him again and he apologised and said he'd got it wrong. He eats 200, like I said before his English ain't so good so I think that was probably the cause of the confusion.

While I agree 6 foot 2 and 220 isn't that big, because the guy's so lean it looks impressive as hell. He doesn't look like a bodybuilder so much as just a bit of a beast.

What sort of protein consumption do you go for? I've been thinking because I'm not as big as this guy and actually eat moreprotein than he does, I might even cut back a bit on the protein and increase my carbs.

"In healthy people with no indication of kidney issues, there is no evidence that high protein intakes are dangerous. For most athletes the biggest danger of high protein intake is that it often comes at the cost of carbohydrate intake."

Most athletes are meeting or exceeding their protein requirements through diet. There are, however, some athletes at risk for inadequate protein. These individuals are typically restricting caloric intake in order to achieve a low body weight and generally include wrestlers, gymnasts, dancers, and runners.[1,5] Inadequate protein intake increases an athlete's risk for injury and chronic fatigue.

It's true that exercise causes muscle breakdown and protein is required to rebuild that muscle during recovery. It's also true that whole body exercises will cause more protein breakdown than isolation exercises, however, the total per workout is likely to be similar if you expend a similar amount of energy in each workout. Therefore, while you do need to make sure you get enough protein, it's the type of workout you do (strength or endurance), not the type of exercises you do that matters.

Certain exercises tend to burn more amino acids when done while on a caloric deficit or low-carb diet.

Whoa! Which exercises?

Anything high intensity, typically. This is assuming a fairly heavy caloric deficit or very restricted carbs, though.

This is a new idea to me. Could you explain more, including how this was determined?

I've read this multiple places...

What do you believe the energy source is in high intensity exercise if glycogen/glucose is not readily available?

Anything beyond the lactic threshold won't use fat for energy, AFAIK.

This is the reason, even though it's kind brosciency, that bodybuilders tend to go low intensity on cardio the closer they get to competition - because as you get leaner and/or cut calorie/carb intake, oxidation of amino acids becomes more prevalent in general.

Doing something high intensity is going to increase gluconeogenesis when carbs aren't available...

Maybe I've misunderstood? You are the doctor, after all ^_^

OH - and I should clarify, I meant high intensity cardio - not weight training.

High intensity weight training is REQUIRED to maintain muscle (by intensity, I mean % of 1RM)

I probably get the most grams of protein a day of anyone that posts here. (and have been called an idiot for it. lol)

I get between 200-300g from shakes a day, depending on the day, and shoot for another 200 or so from solid food.

If I had the time to sit and eat I would do things the other way around, if not 100% from solid foods.

I see my best gains with protein around 400g, which is still less than 2g a lbs for me. If I ate 250g (bodyweight) and the rest in carbs and fat I would be a lard ass and make no muscular gains what-so-ever.

400 a day isn't outrageous, and 4 scoop shakes in 20oz of milk are not sludge in the slightest. I pay just under $10 a lbs for pure protein to be delivered to my door, and eat a lot of tuna, eggs, ground beef and cheap cuts of steak.
